Abstract: In this paper, design principles for implementation of broadband T-type and Y-type power divider based on Substrate-Integrated Waveguide (SIW) technology has been presented. Different design curves have been developed based on simulation results and are used to implement 1×2 power dividers of Y-type and T-type. Finally, by cascading T-type and Y-type stages a 1×4 Power divider of equal division is designed and simulated. The proposed design shows a broad bandwidth (−20 dB) of 18.3% and insertion-loss Bandwidth (1%) of 17.86%.

TL;DR: In this paper, an X-band substrate integrated waveguide (SIW) balun, based on a Y-type divider with enlarged bandwidth, is presented, and the measured amplitude and phase imbalance between two output ports are below 0.7dB and ±3°, respectively.
Abstract: An X-band substrate integrated waveguide (SIW) balun, based on a Y-type divider with enlarged bandwidth, is presented in this study. In most SIW Y-type dividers, the undesired TE

mode either leads to the deterioration of the in-band reflection or constrains the bandwidth by a transmission zero. The cause of the transmission zero is analysed and the modes coupling, rather than the step impedance matching, is utilised to reduce its impact. In the traditional Y-type divider, the frequency band is split by this transmission zero, while in the proposed wideband configuration, the co-existences of the TE

and TE

modes are employed to combine the two non-contiguous bands. A broadband balun is designed and fabricated, with the improved Y-type wideband divider serving for the power-dividing part. The dividing ports are connected to the reversely placed transitions, achieving inherent out-of-phase performance and good amplitude property. The measurement of the balun suggests a 43.94% bandwidth from 8.23 to 12.89GHz, with 15dB return loss. The measured amplitude and phase imbalance between two output ports are below 0.7dB and ±3°, respectively. The performance of the fabricated balun is in agreement with the simulation, and it is promising for wideband applications.

TL;DR: In this article, a single-layer ground-loaded compact SIW-based equal power divider is proposed for wideband and out-of-phase operation by creating defects in the ground plane with rectangular slots.
Abstract: In this paper a novel Substrate Integrated Waveguide (SIW) based single layer ground-loaded compact wideband out-of phase equal power divider is proposed . The wide-band and out-of-phase operation of the proposed power divider is obtained by creating defects in the ground plane with rectangular slots. The Defected Ground Structure (DGS) allows the power divider to exhibit a wide passband. The obtained passband is 11.5 GHz wide considering the return loss better than -10dB. Compactness in the proposed design is attributed to the dispersion characteristic of the slow-wave. The proposed design working in the passband from 14.5 GHz to 26 GHz is fabricated and tested. The size of the proposed design is 0.57 λ2 g excluding feed lines. Here λg is the guided wavelength at free space. The measured amplitude imbalance of (0±1) dB is obtained within the passband. The measured and simulated results are compared and found with in good agreement.

TL;DR: In this article, a numerical multimode calibration procedure is proposed and developed with a commercial software package on the basis of a full-wave finite-element method for the accurate extraction of complex propagation constants of the SIW structure.
Abstract: The substrate integrated waveguide (SIW) technique makes it possible that a complete circuit including planar circuitry, transitions, and rectangular waveguides are fabricated in planar form using a standard printed circuit board or other planar processing techniques. In this paper, guided wave and modes characteristics of such an SIW periodic structure are studied in detail for the first time. A numerical multimode calibration procedure is proposed and developed with a commercial software package on the basis of a full-wave finite-element method for the accurate extraction of complex propagation constants of the SIW structure. Two different lengths of the SIW are numerically simulated under multimode excitation. By means of our proposed technique, the complex propagation constant of each SIW mode can accurately be extracted and the electromagnetic bandstop phenomena of periodic structures are also investigated. Experiments are made to validate our proposed technique. Simple design rules are provided and discussed.

Abstract: A new generation of high-frequency integrated circuits is presented, which is called substrate integrated circuits (SICs). Current state-of-the-art of circuit design and implementation platforms based on this new concept are reviewed and discussed in detail. Different possibilities and numerous advantages of the SICs are shown for microwave, millimeter-wave and optoelectronics applications. Practical examples are illustrated with theoretical and experimental results for substrate integrated waveguide (SIW), substrate integrated slab waveguide (SISW) and substrate integrated nonradiating dielectric (SINRD) guide circuits. Future research and development trends are also discussed with reference to low-cost innovative design of millimeter-wave and optoelectronic integrated circuits.

Abstract: A planar integrated multi-way broadband SIW power divider is proposed. It can be combined by the fundamental modules of T-type or Y-type two-way power dividers and an SIW bend directly. A sixteen way SIW power divider prototype was designed, fabricated and measured. The whole structure is made by various metallic-vias on the same substrate. Hence, it can be easily fabricated and conveniently integrated into microwave and millimeter-wave integrated circuits for mass production with low cost and small size.
